Demonstrator Unit - 4cylinder 48hp diesel engine, x5 21" rotary cutting decks, strong 10-gauge shell construction is an integral part of this durable deck. No tools are required to change the height of cut, adjustable from 2.5 cm (1 in.) to 10.2 cm (4 in.), in 0.64-cm (1/4-in.) increments. Passcode-protected TechControl display enables quickly setting or changing mowing speed, turning speed, or transport speed to limit variations in performance by different operators. The eHydro transmission traction pump and wheel motors in the new A-model takes performance, traction, and operation to the next level, the pedal effort has been reduced, thus reducing the foot fatigue during many hours of mowing.
